Wood fuel has several environmental advantages compared with fossil fuels. Wood can be continually replenished, which leads to a sustainable and dependable supply. However, proper forest management must be practiced to ensure that growing conditions are not degraded during biomass production.
There is little net production of carbon dioxide from wood combustion, because the CO2 generated during combustion of wood equals the CO2 consumed during the lifecycle of the tree. Transporting the material using petroleum generates excess CO2.
Question details (performance):Black smoke happens during operating. Answer: Fault reason:(1) Insufficient air volume, improper air distribution, low furnace temperature: boiler usually equipped with air preheater, but when the air preheater has leakage, hot air flow doesn't satisfy the need of burning, smoke will happen.(2) In the case of stalling situation in full automatic oil-fired boiler: significant increase of furnace negative pressure, no flame can be seen from the inspection hole, steam pressure and steam temperature drop, the steam flow decreases sharply. The water level drops suddenly and then rises sharply.(3) Incomplete fuel burning: this is the main cause of boiler smoke, in the operation, some combustible gases such as carbon monoxide, hydrogen, methane will be generated in addition to carbon dioxide, sulphur dioxide, water vapor and oxygen, nitrogen, etc. during incomplete combustion. They burn and generate black smoke. Incomplete combustion of fuel will not only lead t
Question details (Specific performance):Biomass environmental protection and energy saving fuel made of straw and livestock etc., their combustion is not full. Answer: The cause of the problem:1. Air quantity is insufficient or too big.2. Outer flame position is not proper.Troubleshooting:1.Sufficient temperature： sufficient combustion of biomass boiler needs high temperature, combustion rate is proportional to the temperature, to raise the temperature as much as possible but guarantee there is no slagging.2. Proper air volume. If the air volume is too large, it will reduce the temperature of the furnace and increase the incomplete combustion of fuel. If the air volume is insufficient, the combustion efficiency will be reduced, and the waste of fuel will also increase the emission of smoke.3. Sufficient mixing of fuel and air. During the burning stage of biomass boilers, the sufficient mixing of air and fuel should be ensured and the disturbance should be strengthened during the burnin
